Exhaust Manifolds

Focus On Innovative Exhaust Solutions

An exhaust manifold is a component mounted to a cylinder head of an internal combustion engine. It is used to collect exhaust gases from each cylinder and direct them to a common system whereby gases are treated to remove harmful emissions before being released from the vehicle.

Thirty years ago, we leveraged our industry leading expertise in thin-walled “cored” castings into the production of complex automotive parts and now Wescast is the world’s largest supplier of cast exhaust manifolds for passenger cars and light trucks. We are a Tier I supplier providing exhaust solutions for an extensive range of engines in the global automotive market.
